What kind of fish is this?

[RyanMc]

This fish appeared one day as a very small uncolored fish. There are three other fish that appeared at the same time that have absolutely no color, but this one has orange, yellow, and black patches. They've been in my tank for a couple of months, and now all of the sudden I have a couple more really small ones. I have no clue what they are or where they came from!

Hitchiker fish, how cool... 8)

Not sure exactly what type but it look much like a cardinalfish of some sort.
